A Driver Direction Control Model and its Application in the Simulation of Driver-Vehicle-Road Closed-Loop System 2000-01-2184

The research of driver behavior characteristics has been a focus of vehicle handling and stability performance. With the driver preview effort, many different driver preview models of direction control have been proposed and the simulations of driver-vehicle-road closed-loop system made. But in the simulation, most of the conventional models have the same precondition that the road was simply described as a pre-given preview course. How to simulate the driver dynamically deciding vehicle preview course based on the real road circumstance is the key to the further research of the driver model.

In this paper, a new driver direction control model is established, which is called the Optimal Preview Lateral Acceleration (OPLA) Model and divided into three sub-models: driver’s information identification model, driver’s fuzzy decision model of vehicle preview course and driver’s performance first-order correction model. The simulation results show that this model is able to describe the driver direction control behavior under the real road circumstance through some decision criteria such as drive safety and drive handiness, while driver’s delay character and vehicle dynamics character are also considered. This model also offers an applicable way to the research of the driver-vehicle-road closed-loop syste
